This invention relates to a combination fireproof rooi-jacket and water supply.

An object of this invention is the production of a novel device which will greatly reduce the fire hazard by reason of a smoke pipe extending through the roof of a building, while at the same time a water supply is provided for use by the occupant of the building.

Another object of this invention is to provide a device with a water jacket surrounding that portion of a smoke pipe which extends through the roof, and also to provide in combination with said water jacket an apron that engages the roof to allow water falling on the roof to fill the water jacket.

A still farther object of this invention is to provide an efficient device which has a water jacket, an apron for directing rain water On a roof into said water jacket, and valved means for drawin off water, in a room or building, from said water jacket.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view partly in vertical section and partly in elevation of a device constructed in accordance with this invention, while Figure 2 is a top plan view of same.

Referring to the drawings, in which the preferred embodiment of this invention is illustrated, I designates the roof of a building in which a suitable stove 2 is located. A pipe 3 extends from the stove 2 through the roof I. Surrounding the smoke pipe 3- is a water jacket 4, which is open at its upper end and closed at its lower end, fitting tightly upon said pipe 3. This jacket 4 extends at its upper end above the roof l, and extends at its lower end down into the building, as shown in Figure 1.

On the water jacket, and near its lower end, is a discharge pipe 5 that has a valve 5 for manually controlling the discharge of water from water jacket 4. Therefore, the occupant can, draw off hot water when the stove 2 is working.

On the upper end of the water jacket ii is a discharge spout i so that any overflow can be discharged irorn the water-jacket on to the roof I in an eificient manner.

A flat, substantially V-shaped apron or pan 8 has its inner, smallest end ll resting on or secured to the upper edge of said water jacket;

(Cl. l26364) this end H is spout-shaped, whereby rain water is efficiently discharged into the water-jacket 4. The outer end of the apron rests upon the roof, and by reason of the apron being provided with edge flanges 9, water will be directed to the inner end of the apron. The apron 8 is most efficient because the inlet or outer end is wide and causes a large quantity of rain to enter the apron, insuring that the water jacket is full most of the time.

While I have described the preferred embodiment of the invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

l. The combination with an inclined roof having a smoke pipe projecting therethrough; a cylindrical jacket body projecting through the roof and surrounding the smoke-pipe, said body having a bottom hermetically sealed to said smoke-pipe, and a water conveying trough projecting from the upper edge of the body and resting on the roof at a point higher than the top of said body.

2. The combination with an inclined roof having a smoke pipe projecting therethrough; a cylindrical jacket body projecting through the roof and surrounding the smoke-pipe, said body having a bottom hermetically sealed to said smoke-pipe, and a water conveying trough projecting from the upper edge of the body and resting on the roof at a point higher than the top of said body, said trough having flanged sides flaring from said body and being provided with a flat edge resting on the roof.

3. The combination with an inclined roof having a smoke pipe projecting therethrough; a cylindrical jacket body projecting through the roof and surrounding the smoke-pipe, said body having a bottom hermetically sealed to said smoke-pipe, and a water conveying trough projecting from the upper edge of the body resting on the roof at a point higher than the top of said body, and a valve drawoff pipe connected to the lower part of said body.

4. The combination with an inclined roof having a smoke pipe projecting therethrough; a cylindrical jacket body projecting through the roof and surrounding the smoke-pipe, said body having a bottom hermetically sealed to said smoke-pipe, and a water conveying trough projecting from the upper edge of the body and resting on the roof at a point higher than the top of said body, said trough having flanged sides flaring from said body, being provided with a flat edge resting on the roof and a valve drawofi pipe connected to the lower part of said body.

5. The combination with an inclined roof having a smoke pipe projecting therethrough; of a jacket protecting the roof from the heat of the smoke pipe and including a cylindrical jacket body projecting through the roof and surrounding the said pipe, said body having a bottom hermetically sealed to said smoke pipe, and trough means leading from the upper part of the roof to the jacket.

6. The combination with an inclined room having a smoke pipe projecting therethrough; of a jacket protecting the room from the heat of the smoke pipe and including a cylindrical jacket body projecting through the roof and surrounding the said pipe, said body having a bottom hermetically sealed to said smoke pipe, trough means leading from the upper part of the roof to the jacket, and a valved draw-off pipe connected to the lower part of said body.
